Justin Bieber's single mom, Pattie Mallette, tweeted a photo of herself and "Bachelor" host Chris Harrison on Wednesday. "Had a great night with Chris Harrison!" she wrote. "Thanks Ryan Seacrest for setting it up."

In the picture, Mallette, 36, poses with Harrison, 41, from what appears to be backstage at Bieber's Oct. 3 concert at the Staples Center in Los Angeles. "Huge thanks to Justin Bieber and Pattie Mallette for an incredible night," Harrison also tweeted. "Huge cool dad points! Great show!"

As for Mallette, she hasn't been dating in order to focus on her son's career. "I told Justin I would focus on him and wait until he was 18 when I started dating," she revealed to Ellen DeGeneres last month. So now that Bieber is 18, DeGeneres said, "I got you six months on Match.com. My treat!"
